I have a 2012 gmc terrain 2.4l currently at 202k. I’ve used Lucas oil and restore and protect Valvoline oil the last 50k. Still runs like a gem with 177-182-179-175 compression cylinders 1-4. Used to be 155-149-144-168 before I started using both these oils
LUCAS power steering fluid is great. The spray on wax is magic. After it sits a week, it seems even better. Aluminum too. The gear oil is great.
I exclusively have used Lucas oil for my sportster motor for 5 years. The bottle looks cool, that's it. Full synthetic oil, no frills, cheap, and easy to get.
I found a Lucas replacement on Euro Car Parts that says it fits my car and has 3yr warranty. I checked the specs and it's actually rated at 235 Amps.
I try to use Lucas every few fillups. Always have and I’m setting on 160k.
I like the Lucas ones personally.
Driving from the Alabama - Tennessee line to the gulf coast, most downhill I mind you - predominantly interstate, I have never gotten more than 23. This was with little to no load, Nitrogen tires, Fresh air filter & oil, premium fuel, & Lucas fuel tx additive.
Lucas OS works great. It's some amazing stuff, BUT. Do not go over your oil change intervals. Once the Lucas additive starts breaking down it turns to a nasty varnish. Went 7k using synthetic amsoil z-rod and Lucas OS, on a new rebuilt 4.0l. Lost a lifter and ate up the cam lobe.
Rear Lucas calipers always worked ok-ish after each "fix". But that was never a long term solution. Worked fine for a month, sometimes a year or two. Just a never ending dragging story, uneven pads wear, pads cut at an angle, heat induced accelerated rust of disc and back plate.
I added Lucas to my Hemi Durango and it f*%ked it up….for real!
